asp.net-mvc - Ajax.BeginForm和验证

Question

客户端验证不适用于Ajax.BeginForm

这是我的代码:

<div id="report">
    <div id="projectReport">
        <div >
            @{
                Html.EnableClientValidation();
            }

            @using (Ajax.BeginForm("AnalyticsDates", new AjaxOptions
                {
                    InsertionMode = InsertionMode.Replace,
                    UpdateTargetId = "reportContent"
                }))
            {
                @Html.LabelFor(m => m.StartDate)
                @Html.TextBoxFor(m => m.StartDate, new { id = "start" })
                @Html.ValidationMessageFor(model => model.StartDate)
                @Html.LabelFor(m => m.EndDate)
                @Html.TextBoxFor(m => m.EndDate, new { id = "end" })
                @Html.ValidationMessageFor(model => model.EndDate)
                <input id="btnsearch" type="submit" value=@Titles.Search class="iconHeader"/>
            }
        </div>
    </div>
    <div id="reportContent">
    </div>
</div>

我在web.config页面中启用了验证:

<add key="ClientValidationEnabled" value="true" />   
<add key="UnobtrusiveJavaScriptEnabled" value="true" />

并添加了js文件

<script src="@Url.Content("~/Scripts/jquery.validate.min.js")" type="text/javascript"></script>
<script src="@Url.Content("~/Scripts/jquery.validate.unobtrusive.js")" type="text/javascript"></script>

与第一个有关的第二期，
我的行动是

[HttpPost]
        [Authorize(Roles = "XXXReport")]
        public async Task<ActionResult> AnalyticsDates(ReportRequestVM reportRequestVM)
        {
            if (!ModelState.IsValid)
            {
                return View("**MainReports**", reportRequestVM);
            }

            // fill reportRequestVM with data
            return View("**PartialReport**", reportRequestVM);


        }

如果模型有效，则返回部分 View ，页面看起来不错，否则，返回带有表单的主 View ，但在此页面中，它两次自我渲染。问题是，如果客户端验证失败，如何返回带有验证错误的主表单？

任何帮助，将不胜感激，

我想到了...
您应该对结果和查询有部分看法。

如果失败，则应返回“http错误请求”，并使用以下命令在搜索局部 View 上设置验证。

它应该是这样的:

        @using (Ajax.BeginForm("CloudAnalyticsDates", new AjaxOptions
            {
                InsertionMode = InsertionMode.Replace,
                UpdateTargetId = "reportContent",
                OnFailure = "OnCloudAnalyticsFailure",
                OnBegin = "ValidateForm",


            }))
        {
            @Html.LabelFor(m => m.StartDate)
            @Html.TextBoxFor(m => m.StartDate, new { id = "start" })
            @Html.ValidationMessageFor(model => model.StartDate)
            @Html.LabelFor(m => m.EndDate)
            @Html.TextBoxFor(m => m.EndDate, new { id = "end" })
            @Html.ValidationMessageFor(model => model.EndDate)
            <input id="btnsearch" type="submit" value=@Titles.Search class="iconHeader"/>
        }
    </div>
</div>

<script type="text/javascript">
    $(document).ready(function () {
        $("#datePicker").kendoDatePicker();
        $("#start").kendoDatePicker().data("kendoDatePicker");
        $("#end").kendoDatePicker().data("kendoDatePicker");
    });


    function OnCloudAnalyticsFailure(parameters) {

        $('#projectReport').html(parameters.responseText);
        $('#reportContent').empty();
        CleanValidationError('form');
    }



</script>

在服务器上，它应该看起来像:

[HttpPost]

    public async Task<ActionResult> CloudAnalyticsDates(ReportRequestVM reportRequestVM)
    {
        if (!ModelState.IsValid)
        {
            Response.StatusCode = (int)HttpStatusCode.BadRequest;
            return PartialView("_ReportQuery", reportRequestVM);
        }


        reportRequestVM.BomTotals = await CommonRequestsHelper.GetBomTotalAnalytics(bomTotalRequest);
        return PartialView("_ProjectReport", reportRequestVM);
    }
